(1) The use of Sodium fluosilicate is wide.

(2) The thermal expansion coefficient of fluosilicate glass-ceramics is mainly affected by the crystal phases and their amount.

(3) The potassium fluosilicate produced by this process is possessed of high purity good quality, lower production cost.

(4) The process of preparating potassium fluosilicate from the mother liquor of magnesium fluoride has been studied.

(5) The three precipitates of aluminum fluoride, potassium fluosilicate and silica gel would form at low displacement[/fluosilicate.html], while the aluminum fluoride and silica gel precipitates at high displacement.

(6) The classical potassium fluosilicate precipitated alkali titration method was changed to molybdenum-blue-ness spectrophotometry to fast determine silicon .

(7) Compositions, crystallization mechanisms and properties of the fluosilicate glass ceramics were investigated in this paper.

(8) The method of determination of silicon in Mn - Si alloy with potassium fluosilicate titration is introduced. On the best test condition, disturbance element is removed.
